To all whom t may concern.'

Be it known that I, JOSEPH SAGAN, a subject of the Emperor of Austria-Hungary,

residing at No. 208 Pine street, North Side, Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Flushing-Conduit, ofwhich the following is a specification. j 1

This invention relates to a flushing oo nduit arranged to be installed in the centers of streets or roadways. f

One ob'ect of theinvention is to provide flushing conduit which may be perinanently installed7 and which is arranged to project a substantially unbroken stream or sheet of water into the street along the en` tire length of the conduit in such manner that it will flush the same on both sides of the conduit from `points immediatelyadjacent thereto outwardly to the sides or gutters of the street. A further object of the invention is to provide a conduit which, in. addition to the advantages above stated, is so arranged thatV it is normally in position to perform the flushing operation, and which is adequately protected `from the jars and stresses of traiic.

in the accompanying drawings, Figure 1 is a diagrammatic plan viewA illustrating .a plurality of intersecting streets and the position in which the flushing conduit is designed to be placed thereinyFig. 2, 1s a plan "view with parts broken away showing a portion of the conduit in position in a street or roadwa.T and Fig. 3 is a cross sectional view on the line 3 3 Fig. 2.

ln order to illustrate the-adaptabilityp the conduit to the conditions existing in city streets, Fig, 1 shows aplurality of intersecting' streets 1, 2, and 3 with blocks of buildings 4 arranged therealong, and the conduit indicated at 5 laid in the center of the streets. As shown, the conduit may be lald between the tracks of a single car line, as shown in the street 3, or between the lines of a double tracked street 1, the street 2 having no car track thereon. When thus 1nstalled the sections or systems of conduit may receive water from any convenient source, as from hydrants diagrammatically indicated at 6, or the system of conduitrnay be continuous and supplied from a single adequate source.

The conduit comprises a pipe of semicylindrical form arranged to be contained in a casing 8 which is in the form of a block having a longitudinal cavity 9 oi greater dimensions than those of the pipe and arranged to provide a space between the pipe and casing so as to permit of a slight vertical movement of the pipe therein; the casing being provided with a footing 11 embedded in the structure .of the street. The casing 8 is provided with a pair ci longitudinal projections 8a which extend into the longitudinal `cavity or channel) of the casing and contact the pipe in its normal or raised position therein. On the upper, and substantially plane, surface 12 of the pipe 7 is a guard member 13, secured thereto by suitable bolts or set screws 14 and projecting slightly beyond the sides of the pipe. This guard member also serves to spread and direct jets of water issuing from the orices 15, which are located immediately beneath the upper surface 12 on both sides of the pipe. These. outlets or orifices 15 are upwardly and outwardly inclined and fiarc downwardly and outwardly; the guard 13 being provided at its lateral extremities with short depending portions 16 overlying the orifices 15, and with grooves 16a in its under surface arranged to match with the orifices. By means of this construction the Water does not issue from the conduit in jets, but is spread and directed along the surface oi' the street or roadway from the mouths of the oriiices in a substantially unbroken stream or sheet, so that the full cleansing eii'ect is obtained throughout the entire width ofthe street on both sides of the conduit and no objectionable upwardly directed jet or spray is produced.

'In order toyieldingly support the pipe Z in its upward or operative position, it is provided at intervals along its lower face with aplurality oi stems 17 resting upon relatively strong helical springslS in recesses 19 in the casing 8. By means of the springs 18 the pipe is normally maintained in its raised position projecting slightly above the upper extremity of the casing. but upon the passage of vehicles over the pipe it is so depressed, against the resistance of the springs7 that the depending portions 16 of the guard rests upon the upper sur- :face of the casing which is slightly beveled. along its inner edges. The upper surface of the guard 13 then lies substantially flush with the surface of the street or roadway and protects the pipe from injury. ln its raised or operative position the pipe is promets., j N i tected from lateral displacement in the cas ing by means of the portions 8'nl projecting into the cavity or channel 9 in which the pipe lies, and is Jthus protected from injury due to jarring of the pipe against the interior of the casing. This engagement between the pipe 7 and the projections 8a also serves in some degree to prevent the entrance of refuse into the space between the pipe and the casing.

It will be thus seen that the flushing conduit above described is one which lies normally in operative position, and which requires no manual operation to raise the same for use or to depress it for protection against injury. It is, moreover, so arranged that .water is projected in a stream or sheet throughout the entire length of the conduit fromboth sides thereof, and from a point immediately adjacent the conduit, so that the street or roadway is iiushed from its crown outwardly to the gutters by means of a current directed toward the sides of the street. The conduit is moreover so arranged that no upward jets or sprays are caused and the flushing effect is uniform from the sides of the conduit itself outwardly to the sides or glitters of the street or roadway. The construction of the conduit `is simple and such that the pipe may be readily removed from position in the street for repairs or replacement or for cleansing of the cavity in the casing in which the pipe lies.

What I claim is l. A flushing lconduit comprising a horizontally disposed casing having its upper extremity substantially flush with the surface of the ground in which it is laid, a pipe provided with discharge orifices adjacent the upper face thereof in said casing, a guard secured to the upper face of said pipe, and resilient means arranged to normally support said pipe with its upper face projecting above the upper extremity of said casing.

2. Aflushing conduit comprising a horizontally disposed` casing having its upper extremity substantially flush with the surface of the ground in which it is laid and having longitudinal projections extending interiorly thereof, apipe in said casing provided With discharge orifices adjacent the upper face thereof, and resilient means arranged to normally support said pipe in contact with said projections and with its upper face projecting above the upper extremity of said casing.

3. A. flushing conduit comprising a horizontally disposed pipe provided with discharge orifices adjacent its upper face', a guard secured to said pipe and overlying said orifices, and resilient means for yieldingly supporting said pipe in operative position relative to the surface of the ground inV which it is laid. Y

4. A. iushing conduit comprising a horizontally disposed casing having vertical recesses therein, resilient members in said recesses, and a pipe in said'casing, said pipe being provided with discharge orifices and with stems arranged to enter the recesses in said casing and contact the resilient members therein. 4

5. A flushing conduit comprising a horizontally disposed casinghaving its upper extremity substantially iiush with the surface of the ground in which it is laid and having vertical recesses therein, resilient members in said recesses, a pipe kprovided with discharge orifices adjacent its upper face and having stems arranged to extend into said vertical recesses and contact the resilient members therein, and a guard secured to said pipe and overlying said orifices.

6. A flushing conduit comprising a hori- Zont'aliy disposed casing having its upper extremity substantially flush with the surface of the ground in which it is laid and provided with longitudinal projections extending iiiteriorly thereof and with vertical recesses, resilient members in said recesses, a pipe in said casing provided with discharge orifices adjacent the upper face thereof and having stems extending into said recesses Y SARA Coonn.
